Well, I finally got my car back today from the dealership (KENDRICK CADILLAC IS TERRIBLE). They installed the 06+ diff this time and a new differential vent. I asked them about whether or not they put the limited slip additive in the diff fluid and they said no. I told them it was required, and they told me that they get their differentials partially filled and that the additive was already in there. Does this sound right?????
